Despite the embarrassment of being denied from the prestigious lounge, the 60-year-old brushed it off, telling the Financial Review "It was no trouble at all."
“I was more than happy to be downgraded to the (regular) club,” he added.
After Julie herself was asked about the awkward incident involving her ex, she coyly remarked, "Wait until he finds out about the Chairman's Lounge".
Realising his name would also likely already be removed from the Qantas Chairman's Lounge, Panton commented, "I could always try my luck with my Qantas Chairman’s Lounge membership … but probably won’t. I’ll just be happy in the Qantas Club again."
The hostility between the pair began after David announced his split with the former Liberal leader back in July, where he released a statement that read: "I'm going to be focused on living in Manly and Melbourne for the foreseeable future.
"I wish Julie all the best in her ongoing stellar career."
Bishop did not respond to the statement at the time.
Julie and David are believed to have begun dating around 2014 when they were first seen in public together.
